Studies on sulphur–nitrogen compounds. Part 3. Crystal and molecular structure of triphenylarsine–trisulphur tetranitride (1/1)

Abstract

The crystal structure of triphonylarsine–trisulphur tetranitride(1/1) has been solved from diffractometer X-ray single-cystal data by heavy-atom methods and refined by full-matrix least-squares methods to a final R of 5.0 for 2324 observed reflections. Crystals are of space group P2₁/n with unit cell dimensions a= 12.860(11), b= 13.259(11), c= 11.786(12)Å, β= 103.33(6)° and Z= 4. The triphenylarsine group is bonded through nitrogen to an (SN)_x ring, five members of which are planar.
